To all whom it may concern:

Be it known that I, CALVIN H. BARKDULL, a citizen of the United States, and a resident of Seattle, in the county of King and State of Washington, have invented certain new and useful Improvements in Systems of Camouflage, of which the following is a specification.

My invention is an improvement in systems of camouflage, and has for its object to provide a system of the character specified adapted for use with vessels, fortifications of all characters, aeroplanes, tanks and the like, wherein means is provided for discharging oil, smoke, steam, chemicals or the like from the sides of the vessel, to conceal the same or for any other purpose, as, for instance, to keep the sides of the vessel clear from ice, for cooling the vessel or for quieting the waves by the discharge of oil.

In the drawings:

Figure 1 is a side view of a vessel provided with the improved system;

Fig. 2 is a top plan view, with parts broken away;

Fig. 3 is a transverse vertical section;

Fig. 4 is a section on the line 44 of The present embodiment of the invention is shown in connection with a vessel 1 of conventional type, and the improve ment comprises a series of pipes arranged upon each side of the vessel, in the present instance three series of pipes being provided at each side.

In each series thereis a large pipe2, an intermediate pipe 3 and a small pipe 4, the pipes being arranged in spaced approximately parallel relation, with the pipe 4 near the waters edge, while the pipe 2 is near the deck level. Each of these pipes has openings or perforations in its outer side, and through these openings is adapted to be discharged oil, smoke, steam or any other desired material.

The pipes 2 are more especially adapted for the discharge of smoke, the pipes 3 for the discharge of steam, and the pipes 4 for the discharge of oil, and it will be noticed that the ends of all the pipes are closed, as indicated at 6, at both their front and rear ends, and that the said pipes extend to near the stern and near the bow.

The pipes 2, as shown more especially in Figs. 3 and 4, are jacketed, each pipe having a jacket 7 inclosing the same, and passages 8 are provided at the outer sides of the pipes, leading from the pipes to the jacket and opening through the jacket, to

permit the smoke to be discharged from the pipe 2 to the open air. At approximately the center of thepipe 2 there is provided a connectlon between the said pipes and the smoke stack 9 of the furnace, This connection is a pipe 10 leading from the stack outwardly toward the side of the vessel, and each pipe has a dependingportion 11 adacent to the vessel wall.

Other pipes 12 diverge from the portion 11 of the pipe 10 at the level of the pipes 2, and extend through the wall of the vessel and through the wall of the jacket 7 to a connection with the pipes 2. A valve 13 is arranged in each pipe 12 for controllin the same, and there is an extension 14 0% the acket 7 about that portion of each pipe 12 ad acent to the pipe 2, the said extensions passing through the vessel wall.

Each of these extensions 14 has connected therewith a water pipe 15, by' means of which the pipes 2 may be cooled, the'water flowing through the extensions and through the jackets to cool the same to prevent injury to the vessel wall. Valves 16 are arranged in the pipes j 10, between the stack and the pipes 12, and a fan 17 is arranged in each of the said pipes between the valve and the stack.

A pipe 18 extends from the condenser pump to near the pipes 12, where the said pipe branches and the branches 19 open into the pipes 12 at the extensions 14. A valve 20 is arranged in each of the branches for controlling the same.

The pipes 3 are supplied with steam from the dome21 of one of the boilers 22 by. means of pipes 23 which extend laterally and forwardly from the dome toward the vessel wall. Each of these pipes 23 branches at the depending portion 11 of the pipe 10, and each branch 24 is connected with the adjacent pipe 3.

Referring to Fig. 4 it will be noticed that partitions 25 are arranged in the pipe 2 at the openings of the pipes 12, the said partitions being arranged on the inner sides of the said openings, so thatthe smoke must flow toward each end of the pipe 2. The

same arrangement obtains in the pipe 3 between the branches 24, and each branch24 has a valve 26 for controlling the same. The

pipes 3'and 4 have openings or perforations,

as shown in Fig. 1, extending the fulllength thereof and arranged in spaced relation, and
